Questions are increasingly being asked regarding the faith of nutrient components such as proteins, minerals, vitamins, and lipids after feed formulation. The aim of this review is to evaluate the evidence with the perspective of fiber usage in feed formulation. The consumption of dietary fiber may affect the absorption of nutrients in different ways. The physicochemical factors of dietary fiber, such as fermentation, bulking ability, binding ability, viscosity and gel formation, water-holding capacity and solubility affect nutrient absorption. The dietary fiber intake influences the different methods in which nutrients are absorbed.

  • Mineral Absorption & Deficiency
    Mineral Absorption & Deficiency Mineral Absorption and Deficiency By Yvette R. Schlussel, Ph.D. Rutgers University Summary Conclusions A wide range of minerals is essential for human health. The recommended dietary allowances (RDAs) serve as guidelines for daily intakes of nutrients that population groups in the United States should have in their diets. Dietary Reference Intakes (DRIs) have been established for the following essential minerals: calcium, phosphorus, and magnesium. In addition, DRIs have been set for other trace elements, which have been identified to have important-if not essential roles in maintaining health. These include: iron, zinc, copper, manganese, selenium, boron, chromium, cobalt, molybdenum, vanadium, nickel, lithium, iodine and fluoride(1). There is evidence that the need for mineral intake is not being met, especially in certain subpopulations. It is difficult for most individuals to ingest enough calcium from foods available in a cereal-based economy without liberal consumption of dairy products, for example.(2) Supplementation with minerals is recommended to complement dietary intake and avoid deficiencies. (3) Mineral supplements are associated with different absorptive capacities. The absorption of minerals depends on a number of physiological, biochemical, and hormonal characteristics of the consumer and the form of the mineral consumed. Potential mineral sources are not all alike and should be evaluated for bioavailability.(4) Factors that enhance mineral absorption include the form of the mineral ingested, maintenance of chemical stability, presence of a specific transporter, small particle size, solubility, ascorbic acid, and low intestinal motility. Factors that inhibit absorption include oxalic acid, phytic acid, (5) fiber(6), sodium, tannins(7), caffeine, protein, fat, antacids, rapid transit time, malabsorption syndromes, precipitation by alkalinization, other minerals(8), hormones and nutritional status(9).

Instead, the trend for increased species diversity in swards is an opportunity to improve mineral concentrations in the basal diet. Currently, there are limited data on the mineral concentrations of different species and botanical groups, particularly for I and Se, which are among the most deficient minerals in livestock diets.

The latter elements are typically excluded from the discussion of plant mineral nutrition because they are assimilated from the atmosphere and from water. Mineral nutrients are so named because they are primarily derived from the weathering of minerals of the Earth's crust, with the exception of nitrogen, which is primarily derived from atmospheric nitrogen. Taken together, these nutrient elements are critical for the processes of plant growth and hence are key to the capturing of solar energy, which is the basis of nearly all life on Earth.

Water culture (hydroponic) techniques were subsequently employed to characterize the nature of how plants gained matter. In the nineteenth century, Justus von Liebig advanced the notion that soil per se was not required for plant growth, but that it contributed soluble inorganic constituents.

The aim of the study was to determine the effect of citric acid (CA) applied in a nutrient solution on the composition of the pore water of a calcareous soil and its correlation with the chemical composition and quality of the tomato plants and fruits. The experimental design was a randomized block; the treatments were different concentrations of CA added to the Steiner nutrient solution. We used CA at 10- 2, 10-4 and 10-6 M and a test treatment without CA. A decrease in the electrical conductivity (EC) and oxidation-reduction potential (ORP) was observed in soil pore water (SPW), as well as changes in the concentrations of Ca2+, Mg2+, Na+ and K+ in response to the addition of CA. The concentrations of Zn, Na, Ca, and N increased in leaves, whereas in the fruit, the concentrations of Mn, Na, Mg, and P increased. Significant correlations arise between Na+ and Mg2+ (R=0.60), Na+ and Ca2+ (R=0.68), and Mg2+ and Ca2+ (R=0.76) in the soil pore water, as well as a significant negative correlation (R=-0.73) between the concentration of K+ in the soil pore water and the concentration of Mg in stems and leaves.

  • Importance of Dietary Phosphorus for Bone Metabolism and Healthy Aging
    nutrients Review Importance of Dietary Phosphorus for Bone Metabolism and Healthy Aging Juan Serna 1 and Clemens Bergwitz 2,* 1 Yale College, Yale University, New Haven, CT 06511, USA; [email protected] 2 Section of Endocrinology and Metabolism, Department of Internal Medicine, Yale School of Medicine, New Haven, CT 06519, USA * Correspondence: [email protected] Received: 20 August 2020; Accepted: 26 September 2020; Published: 30 September 2020 Abstract: Inorganic phosphate (Pi) plays a critical function in many tissues of the body: for example, as part of the hydroxyapatite in the skeleton and as a substrate for ATP synthesis. Pi is the main source of dietary phosphorus. Reduced bioavailability of Pi or excessive losses in the urine causes rickets and osteomalacia. While critical for health in normal amounts, dietary phosphorus is plentiful in the Western diet and is often added to foods as a preservative. This abundance of phosphorus may reduce longevity due to metabolic changes and tissue calcifications. In this review, we examine how dietary phosphorus is absorbed in the gut, current knowledge about Pi sensing, and endocrine regulation of Pi levels. Moreover, we also examine the roles of Pi in different tissues, the consequences of low and high dietary phosphorus in these tissues, and the implications for healthy aging. Keywords: dietary phosphorus; inorganic phosphate (Pi); hypophosphatemia; hyperphosphatemia; mineralization; absorption; paracellular; transcellular 1. Introduction Phosphorus is one of the essential elements of the human body and is required for a diverse range of processes, such as ATP synthesis, signal transduction, and bone mineralization. The vast majority (85%) of phosphorus in the body exists as a component of hydroxyapatite [Ca10(PO4)6(OH)2] in the extracellular matrix of bone and teeth [1].

Ustin, Professor California Space Institute Center of Excellence, One Shields Ave. The Barn University of California, Davis, CA 95616-8527, United States. [email protected]; [email protected] Alicia Palacios Orueta, Professor Titular Escuela Tecnica Superior de Ingenieros de Montes, Universidad Politecnica de Madrid, Madrid, Spain. [email protected] Lin Li, Assistant Professor Department of Geology, Indiana University - Purdue University, Indianapolis, IN, United States. [email protected] ABSTRACT High spectral resolution of hyperspectral images promise mineral identification and abundance estimates of bare soils for advancing precision farming and carbon cycle modeling. Under desiccated conditions, investigators have shown that band parameter measurements (position, depth, width, and derivatives) can be used as reliable estimators of mineral type and contents. With moisture, even air-dried soil, the water absorption fundamental and combination absorptions reduce accuracy of mineral estimates as soil albedo declines and mineral absorption band-depths diminish. The effects of water on soil albedo were accurately modeled by extrapolating the shortwave infrared (SWIR, 1.0 to 2.4 m) continuum to the water fundamental center at 2.8 m using an inverted Gaussian function, that is located beyond the range of common airborne and field hyperspectral instruments. This improves accuracy of water estimates over modeling the water content using specific water bands (principally, 1.4 and 1.9 m) since these bands are susceptible to saturation by atmospheric water vapor beneath airborne and satellite platforms. In contrast, our soil moisture Gaussian model (SMGM) provides an accurate measure of soil moisture for use with other band metrics in spectral mixture analysis or classification and regression classification models for mapping mineral abundance of surface soils.
